The evolution of industrial welding inevitably involves automation, precise control, and intelligent integration of technologies. With this in mind, Isotron developed the model IS-50D MF-SR, a spot welding machine designed to meet the demands of rotor welding with maximum efficiency and safety.
What is the IS-50D MF-SR?
The IS-50D MF-SR is a medium frequency spot welding machine, developed for welding processes of electric rotors, such as those used in automotive motors and alternators. The equipment combines power, electronic control, and integrated mechanical solutions, ensuring high-quality welds with excellent repeatability.
Designed for industrial applications with high production volume, the machine offers a semi-automatic welding cycle, with features that reduce operation time, increase operator safety, and improve energy performance.
Technology and Technical Data
The main differentiator of the IS-50D MF-SR lies in its medium frequency welding system (MFDC), which uses an IMF-15 inverter to raise the electrical network frequency from 60 Hz to 1,000 Hz, resulting in a more stable and efficient direct current.
Main technical characteristics:
- Power supply: 380V three-phase
- Nominal power: 60 kVA
- Operating frequency: 1,000 Hz
- Current control: closed loop, constant current
- Program capacity: up to 250 configurable cycles
- Welding current: 1.5 to 15 kA
- Operation interface: HMI Plus with program selection and parameter monitoring
Integrated Equipment and Solutions
To ensure the stability and quality of welding, the IS-50D MF-SR incorporates various subsystems and complementary devices:
- ISOTRON MF2-8 transformers with digital control
- Automatic rotating table with customized cradles for rotors
- Welding heads with cooled electrodes
- Pneumatic clamps with positioning manipulators
- Optical sensors and load cells for force control
